Batten roof and sheet metal batten

ABSTRACT

Parallel sheet metal roofing pans having upwardly extending sides with inturned flanges along their upper edges are located at opposite sides of a batten that is in the form of an inverted sheet metal channel having spaced sides connected at their upper edges by a web and having outwardly extending supporting flanges along their lower edges projecting beneath the adjoining pans. Each of the channel sides is cut to provide it with a plurality of tongues spaced lengthwise thereof and integrally connected at one end to the side adjacent the channel web. The tongues are bent upward between the channel sides and adjoining pan sides and then hooked around the adjoining pan flanges to anchor the pans to the batten.

Separate fasteners are used for attaching the pans to the battens. When fasteners such as nails or screws extend through the sides of the pans the holes for the fasteners must be sealed but they always are potential points of leakage.

It is among the objects of this invention to provide a batten roof, in which the battens are formed of sheet metal, in which no separate fasteners for attaching the metal pans to the battens are necessary, and in which there are no holes through the sides of the pans.

The preferred embodiment of the invention is illustrated in the accompanying drawings, in which FIG. 1 is a fragmentary perspective view, broken away in vertical section, of a roof;

FIG. 2 is a fragmentary perspective view of a batten; and

FIG. 3 is a view similar to FIG. 1, but showing a cover applied to the batten.

Referring to FIG. 1 of the drawings, the rafters or roof beams of a roof are covered by a deck 1 of wood or sheet metal forming a continuous surface. At specified intervals along this deck there are battens that are parallel to one another. Each of these battens 2 is made of sheet metal that has been bent into the desired shape, which isan inverted channel having spaced sides connected at their upper edges by a web. Extending along the lower edges of the channel sides and integrally connected with them are flanges 3 that project outwardly a short distance and rest on the deck. These flanges are provided with longitudinally spaced openings 4, through which nails or screws 5 extendthat fasten the flanges to the underlying deck. To allow for differential expansion and contraction between the battens and the deck, the flange openings 4 are slots extending lengthwise of the battens.

Disposed between the battens are sheet metal pans 7. Although these pans could rest on the batten flanges and the deck between the battens, it is highly desirable that they be spaced from the deck by panels or slabs 8 of thermal insulation, such as fiberglass. These insulating slabs rest on the batten flanges and the deck, and the pans are seated on the slabs. Each pan has upwardly extending sides with inturned upper edges forming longitudinal flanges 9. The sides of the pans engage, or nearly engage, the adjoining sides of the battens between which the pans are located.

At the time each batten is made and before it is installed in a roof, integral tongues are stuck out of each side of the batten. That is, as shown in FIG. 2, each side of the batten is cut to provide it with a plurality of tongues 11 spaced lengthwise of the batten and integrally connected at their upper ends to the side of the batten near the web of the channel. Each tongue is formed by making two cuts 12 extending downwardly from near the web and connected at their lower ends by a crosscut I3. If desired, the portion of flange 3 beside the crosscut can be removed. The tongues at one side of the batten are staggered lengthwise of it relative to those at the opposite side so that the batten will be weakened as little as possible by the tongues.

After the battens have been installed, but before the metal pans have been put in Place, all of the tongues are folded upwardly against the sides of the battens as indicated in FIG. 2, so that the tongues extend'above them. Then the pans are inserted between the battens, with the lower portions of the tongues between the battens and the sides of the pans as shown in FIG. 1. The next step is to bend each tongue outwardly across the top of the adjoining flange 9 of a pan and then fold it around the edge of the flange so that the tongue is hooked onto the flange. It will therefore be seen that the tongues hold the pans down and also against the battens. No separate fasteners are required for attaching the pans to the battens. Of more importance is the fact that no nails or screws penetrate the sides of the pans to fasten them to the battens. If there is any difference in longitudinal expansion and contraction between the pans and battens, it can be accomodated by relative sliding between the pan flanges and the batten tongues.

After the pans have been installed in this manner the battens, tongues, and pan flanges are covered by sheet metal cover strips 15. As shown in FIG. 3 in dotted lines, each of these strips is in the form of an inverted channel, in which the distance between its side flanges is substantially equal to the distance between the edges of pan flanges 9 at opposite sides of a batten. The cover strip is placed on top of a batten with the strip flanges extending down below the pan flanges. The cover strip flanges then are folded inwardly toward each other to hook them under the pan flanges as shown. All joints between the pans and batten are therefore concealed and protected from rain and snow by means of the cover strip.

The metal battens are filled with insulation 17 so that along with insulating slabs 8, a solid insulating cover for deck -1 is provided. Furthermore, the insulated battens form better thermal insulation than the customary wooden battens.

In addition to the advantages of this roof referred to above, there are the further advantages that it is quick and easy to install, the battens are always straight and of uniform size, and the difficulty and expense of obtaining wood battens, which are in short supply, are avoided.

According to the provisions of the patent statutes, I have explained the principle of my invention and have illustrated and described what I now consider to represent its best embodiment. However, I desire to have it understood that, within the scope of the appended claims, the invention may be practiced otherwise than as specifically illustrated and described.
